WEAR-TECH PISTON AND SEALS Floating pistons supported by filled PTFE wear bands eliminate metal-to-metal contact and ensure long life. Durable low friction lipseals provide abrasion resistance and guarantee low breakaway pressure.

CHROME ALLOY STEEL PINION AND RACK The rugged, high strength gear train ensures long, dependable life with minimal wear and provides maximum shock resistance.

LOW FRICTION BALL BEARINGS Maximum actuator efficiency and life is obtained by the high capacity ball bearings, which are permanently sealed for maintenance-free operation.

BUILT-IN SHOCK ABSORBER OPTION Built-in shock absorbers dissipate energy and eliminate the need for cumbersome external brackets. This saves space, cost, and simplifies mounting.

ELECTRICAL POSITION SENSORS Proximity switches, Hall Effect, and reed switches are available. A magnet groove is standard on all pistons, allowing field conversion to position sensing switches.
